I’m not sure about any horror stories or any major regression being reported. I can say that 1.43.0 was one of longest betas when it was in beta. It has also been in the public release cycle for almost a month. Most of the issue I’ve seen related to 1.43.0 was actually for our deb/rpm repo and signature processes which wouldn’t apply to Netgear.
Are all your servers running the same version? There was a security issue between 1.41.7.x to 1.42.0.x..
